So if I find some wheels that I like and the offsets are 20 and 25 which are to aggressive for a sedan can I just get a 15mm spacer for the front and a 20mm spacer for the rears if the width of the wheel isn't an issue? thanks

 

no - that would give you a +5 offset

 

^^shane is right. spacers will give you an even more aggressive offset...lol

quite the opposite of what you want to achieve..think about it..they are call spacers, afterall.

 

damn haha ok thanks for setting me straight
